It may seem like your teenager is ignoring you, but in reality, they may be having trouble hearing you. More and more we see kids listening to their MP3 players while doing homework, walking to school or riding in the car. The result? A surge in hearing loss.

For years, studies have shown that constant exposure to loud sound damages hearing. In fact, between the mid-1990s and 2006 there was a 31 percent increase in the prevalence of hearing problems among U.S. adolescents, according to a study by the Journal of the American Medical Association. Researchers suggest that one in every five teens today has some sort of hearing impairment.

Chronic exposure to loud noise may not cause hearing loss in the short term, but it can gradually result in irreversible hearing loss later in adult years. Even slight hearing loss can have a negative impact on a child’s academic success and social interaction. Warning signs of potential hearing loss include: difficulty following directions, asking that things be repeated, trouble with speech and language and listening to the TV at a high volume.

With the prevalence of music devices only gaining popularity, parents need to be particularly aware of their kids’ music-listening habits and educate them about the dangers of excessive noise.

To mitigate hearing loss, talk to your kids about how to use their music players properly to protect their ears from hearing damage.

Teach kids to never play their music devices at full volume.

Monitor your child’s music volume and frequency.

If you can hear the music from the child’s ear buds, then the music is too loud.

Explain to your child the importance of wearing ear protection when they are in an environment with loud noises for long periods of time, such as concerts.

The difficult truth about hearing loss is that in many cases it is not reversible, and it can even be progressive over time. Talk to your kids about the dangers of hearing loss now, and keep the volume and length of their listening to a minimum.

Whenever you have questions about your child’s hearing, talk to your pediatrician.
